Description
Technical field
The utility model relates to the flow control valve in a kind of heating, the heat supplying pipeline.
Background technique
Generally using three-way valve to carry out switch in the heating system of residential building, office building contour level building regulates.But in the network system for managing of central heating at present, the maximum open degree of the employed three-way valve of different floors all is identical, thereby the thermodynamic equilibrium between uncontrollable and regulating course is distributed.Notification number is that the utility model patent of CN2767779Y discloses a kind of intelligent electric stop valve for three-way flow proportional distribution, can be widely used in the heating system, but it also exists the problems referred to above.
The model utility content
For solving the identical problem of the maximum open degree of existing in prior technology, the utility model provides a kind of threeway balance adjustment valve, it comprise have liquid entering hole A, valve body 1, valve rod 2 and the spool 3 of fixedlying connected of liquid outlet B and bypass liquid outlet C with valve rod 2, the stage casing of described spool 3 is provided with the cone that two bottom surfaces coincide, cone and valve rod 2 coaxial lines, it also comprises limiting stopper 4, and described limiting stopper 4 is fixedly installed on the inner chamber of valve body 1 of spool 3 belows.
Further, the utility model also comprises hand knob 5, and described hand knob 5 is fixedlyed connected with the upper end of valve rod 2.
Further, the utility model also comprises the guide holder 6 that has pilot hole, and described guide holder 6 is fixedly installed on the inwall of valve body 1 of spool 3 belows, and the below of described spool 3 is provided with guide rod 3-1, and guide rod 3-1 places in the pilot hole of guide holder 6; And described limiting stopper 4 is fixedly installed on the upper surface of described guide holder 6.
The limiting stopper 4 that the utility model is installed by spool bottom, it can limit the downward displacement amount of spool 3, thus maximum open degree that can control valve, thus the thermodynamic equilibrium of regulating different floor gaps is distributed.It has the characteristics of the simple and reliable operation of rational in infrastructure, technology, and it can solve the problem of the thermal misadjustment in the vertical heating system effectively by carry out manual tune in the scope of maximum open degree.
Description of drawings
Fig. 1 is a sectional structure schematic representation of the present utility model;
Fig. 2 is the D-D sectional view of Fig. 1.
Embodiment
Specify embodiment below in conjunction with Figure of description.
As shown in Figure 1, present embodiment it comprise have liquid entering hole A, valve body 1, valve rod 2 and the spool 3 of fixedlying connected of liquid outlet B and bypass liquid outlet C with valve rod 2, the stage casing of described spool 3 is provided with the cone that two bottom surfaces coincide, cone and valve rod 2 coaxial lines, it also comprises limiting stopper 4 and hand knob 5, described limiting stopper 4 is fixedly installed on the inner chamber of valve body 1 of spool 3 belows, and described hand knob 5 is fixedlyed connected with the upper end of valve rod 2.In use, manual rotary knob 5, the limiting stopper of installing by the spool bottom 4 limits the downward displacement amount of spool 3, thus maximum open degree that can control valve, thus the thermodynamic equilibrium of regulating different floor gaps is distributed.
Particularly, described limiting stopper 4 can be provided with arbitrarily with respect to the axially relative device of spool 3, and then forms different maximum valve flows.Therefore, when the floor practical application, can be installed in bottom by the valve that maximum open degree is big relatively, the valve that maximum open degree is relatively little is installed in top layer, and then guarantees the balance distribution of upper and lower layer user's heating power, has effectively avoided the problem of energy waste.Wherein, described hand knob 5 can be selected multiple mode for use with the mode of fixedlying connected of valve rod 2 upper ends, such as hand knob 5 is provided with internal tooth, and the upper end of valve rod 2 is provided with the external tooth that matches with internal tooth.
Further, it can also comprise the guide holder 6 that has pilot hole, and described guide holder 6 is fixedly installed on the inwall of valve body 1 of spool 3 belows, and the below of described spool 3 is provided with guide rod 3-1, and guide rod 3-1 places in the pilot hole of guide holder 6; And described limiting stopper 4 is fixedly installed on the upper surface of described guide holder 6.In the capable breakdown action process of spool 3 upper and lower shift-ins, the guide holder 6 that is increased has played further guiding and spacing effect, has improved operability of the present utility model greatly.
In addition, described limiting stopper 4 also can be fixedly installed on the guide rod 3-1 of spool 3 bottoms, adopt screw-thread fit between described limiting stopper 4 and the guide rod 3-1, can obtain different maximum open degree according to different use needs adjustment limiting stoppers 4 and the relative axial position between the guide rod 3-1.More than about the specific descriptions of limiting stopper 4, only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all in protection domain of the present utility model.
Further, the utility model also comprises feed liquor temperature transducer 7, offers sensor mounting hole 1-1 on the valve body 1 of described liquid entering hole A end, and described feed liquor temperature transducer 7 is arranged in the sensor mounting hole 1-1.Described feed liquor temperature transducer 7 can accurately be measured the feed liquor temperature, so that calculate and the control use.
Be, the utility model is not limited to the description of mode of execution with being appreciated that, uses needs all in this patent protection domain as long as satisfy.
